Does hand cycling the action on new (less than 300 rounds) SA58 really help for a smoother action (less FTF issues) or is there a better way?????

I hand cycled my second one about 300-400 times before shooting it and it broke in in about 100 rounds and only had to turn the gas down once after the first adjustment. I pulled the extractor off the bolt and put a fired round in the chamber and just kept pulling back smartly and letting it fly forward. The other took about 350-400 rounds to smooth out. The one that I am building now I plan on trying some lapping compound on or stoning the rails first as that seems to be where all the roughness is.
